mb/ocp/deltalake: Add OCP Delta Lake mainboard

OCP Delta Lake server is a one socket server platform powered by
Intel Cooper Lake Scalable Processor.

The Delta Lake server is a blade of OCP Yosemite V3 multi-host
sled.

TESTED=Successfully booted on both YV3 config A Delta Lake server
and config C Delta Lake server. The coreboot payload is Linux kernel
plus u-root as initramfs. Below are the logs of ssh'ing into a
config C deltalake server:
